RADIATOR.

Application filed May 4, 1918.

7 of the objects of the invention is to obtain a construction in which the water is cooled by loosing its heat both through direct con tact with the air and through the evaporation of a portion of the water. Another object is to obtain means for finely dividing the water in its passage through the radiator and for passing the air through the finely divided water. Still another object is to obtain means for preventing the splashing of the water out ofthe radiator. A further object is to obtain a construction in which the screens are removably mounted within the radiator casing. Other objects of the invention reside in the novel arrangements and combinations of parts as more fully hereinafter set forth. 7

In the drawings:

Figure l is a front elevation partly in section of the radiator;

Fig. 2 is a central cross section therethrough.

A is the casing of the radiator, B the water inlet conduit extending from back to front of the casing within its upper portion, and C the receptacle for the water within the lower portion of the casing. The inlet conduit B has the spaced apertures B in its lower half for the passage of the water therefrom in sprays, which diverge. D are the inclined screens, which have their adjacent upper edges detachably pivotedto each other at D and their opposite lower edges removably mounted upon the projections E, formed by the angle bars E secured to the inner sides of the casing A and opposite each other. The pivot D comprises a rod longitudinally slidably engageable in loops M at the upper edges of the screens. The screens D are provided with a series of equally spaced holes of different size, the upper portion of each screen, having the holes of smallest diameter and the lower portion of each screen having the holes of largest diameter. This is for the purpose of providing for the passage of the water Specification of Letters Patent.

through the lower portions of thescreens as v well as the upper portions so that the water is more evenly distributed.

For the purpose of permitting of the passage of air through the radiator to cool the water both through direct contact with the air and through the evaporation of a portion of the water, the opposite sides (the front and rear) of the casing A have the elongated narrow openings F intermediate the inlet conduit B and the screens D,the

elongated narrow oppositely-inclined openings F below the screens D and extending substantially parallel thereto, and also the elongated narrow transversely extending openings F near the center thereof and 1:

below the upper ends of the oppositely-inclined openings F. For directin air into the radiator the inclined guides BI are provided secured to the upper edges of the apertures, F, Fand F The outer portions of these guides extend above the openings and the lower portions extend a substantial distance therebelow. These guides are provided at opposite sides of the casing-so that the air in passing into the radiator'casing takes a downward movement and in passing out takes an upward movement. Due to this latter movement the water, which is not evaporated, will not be carried out of the casing. j I

For the purpose of preventing the splashing of the water out of the receptacle C and through the various openings F and F the receptacle is divided into a plurality of communicating compartments Gr, G and Gr formed by means of the transverselyextending partitions H and H. These compartments communicate by means of the openin s I and I respectively in the partitions and H. For further preventing the splashing of the water out of the receptacle the upper edge of the receptacle 0 has the angle irons J secured to its outer side walls for their complete extent. The flanges J of these angle iron's extend inwardly over the outer portions of the receptacle and thereby prevent the splashing of the water out of the receptacle.

The screens D are secured Within the casing A so that they may be easily taken out of the same and replaced. The pivot D or rod is adapted to slidably pass through an aperture in the front of the casing A and to be slidably removed from-the upper adj acent edges of the screens D and the lower edges of the screens simply' rest upon the flanges and are held in contact therewith, due to the inclination of the screens when pivoted to each other at their upper edges. The casing A has the apertures A in its upper portion above the projections E and at opposite sides for the removal of the screens, which apertures are closed by means of the flaps K, pivotally connected to the top of the casing-A. To withdraw the screens, the pivot D is removed, when the screens can overlap each other and be drawn out through the apertures A. N is a handle secured to the upper edge of one of the screens D for facilitating in the removal of this screen.

he radiator is provided with a suitable trap L at the outlet which connects into the receptacle 0, this trap being for the purpose of separating the sand and dirt from the water before the latter passes back into the engine.

From the above description it is seen that the air directly commingles with the finely divided water so that the water is cooled by'loosing its heat to the air and also by the air carrying off evaporated water, the evaporation of this water cooling the remaining water by absorbing some of its heat. Also the water within the radiator is prevented from splashing out by the partitions and the angle irons around the lower portion thereof.

lVhat I claim as my invention, is:

1. In a radiator, the combination with a casing, of a water inlet in the. upper portion thereof, a receptacle for water in the lower portion thereof, said casinghaving holes in its opposite sides above said receptacle and said receptacle comprising a plurality of compartments for preventing the splashing of the water from the same, said flanges extending partially across said compartments.

2. In a radiator, the combination withthe casing having inwardly-extending projections on opposite sides thereof, of screens within said casing, having their inner ends resting upon each other and their outer ends removably mounted upon said projections, and a water inlet above said screens.

3. In a radiator, the combination with the casing having inwardly-extending projections on opposite sides thereof and openings above said projections, of inclined screens pivotally connected to each other at their adjacent edges, their opposite edges resting upon said projections, flaps for closing said openings in the casing, pivoted to the casing, and a water inlet above said-screens.

4. In a radiator, the combination with the casing having an inwardly-extending projection on one side thereof, of a screen, within said casing and mounted upon said projection, said screen provided with apertures of progressively increasing area from its upper to its lower edge, and a water inlet above said screen.

5. In a radiator, the combination with the casing provided with a shoulder, of a transversely-extending screen removably resting upon said shoulder, a water inlet above said screen, and apertures in opposite sides of said casing and located beneath said screen to permit the passage of air through said casing and beneath said screen.

In testimony whereof I affix my signature.
